ANGLE-IRON SEAT.

Application filed June 30, 1919.

I has for its object elimination of the necessity of mitering the ends of angle-irons, for the purpose of forming a joint, thereby saving the time and expense of such mitering. This invention, furthermore, makes a stronger joint than is provided by former methods.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a perspective view from the outside of such a joint;

Fig. 2 is a vertical and longitudinal sectional view through the device that makes the joint;

Fig. 3 is a perspective view of the device that makes the joint;

Fig. at is a perspective view showing the said device in place joining three angleirons; and

Fig. 5 is a side elevation of the said device.

The device depicted in Figs. 2, 3, and 5 separate from other parts or membersis an integral casting having the central box-like boss 1 and a plurality of arms 2. These arms 2 will be as numerous as the number of angle-irons to be united in one joint. For instance, if only two angle-irons are to be united. there will be but two arms 2. If, however, three angle-irons 3 are to be united, as shown in Figs. 1 and 3, there will be three arms 2, as shown in the drawings. Though integral with the arms 2, the boss 1 can be conceived as having the shape of half of a box or half of a hollow cube. This precise shape is not material, but is mentioned for the sake of giving a clearer idea of what is depicted in the drawings.

The thickness of the said boss 1 is preferably the same or approximately the same as the thickness of the angle-irons 3. The ends of the angle-irons 3 abut the said boss tightly, and are then fastened by rivets 4, which pass through holes 5 in arms 2 and through registering'holes in the flanges of angle-irons 3, and are then upset in the usual manner.

Thus, a very tight and strong joint can be very quickly formed, and without the necessity of mitering the ends of the angleirons 3. The edges .or shoulders 6 of the boss 1 form a brace for the ends of the angle-irons 3; the arms 2 likewise form a brace for the same; and the rivets 4 bind the whole tightly together.

By the drawings, it will be seen that the angle-irons 3 preferably lie exterior to the device that forms this invention,,with the exception of boss 1, that is to say, the angle-irons 3 are the next size larger than the angle-iron arms 2, and thus the flanges of the angle-irons 3 overlie and liealong the flanges of the arms 2, thus forming a lengthwise brace.

lVhile the foregoing is the preferable form, advantages can be derived by using the device shown in Figs. 2, 3, and 5 to receive angle-irons upon its inside instead of, as hereinabove described, upon its outside.

Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims.

I claim:

1. An angle-iron joint comprising as an integral member a chair of angularly related sides and arms projecting from the chair and each comprising plate sections projected in parallelism with two adjacent angularly related sides of the chair and offset therefrom, whereby the arms present right angle sections adapted to receive angle bars on the inner or outer sides of said arms.

2. An integral angle-iron joint comprising a plurality of arms'disposed at right angles to each other, each arm having an inner and outer surface in the same plane as the similar surfaces of an adjacent arm, with each arm made up of right angle plate sections whereby to receive the angle-iron on the inner or on the outer sides of said arms, and a chair forming the corner of the joint with its outer surfaces respectively in parallelism with and offset from similar surfaces of two adjacent arms.

In testimony whereof I hereunto affix my signature.
